Description

Technical Field

[0001] The present application relates to the field of clamping tools, and in particular to a clamping tool for machining non-magnetic bearings. Background Art

[0002] Non-magnetic bearings are a special type of bearing that completely eliminates magnetization and reduces the failure rate associated with magnetic fields. Non-magnetic bearings are usually made of non-magnetic metal materials or suitable plastic and ceramic materials.

[0003] In the prior art, the bearing processing equipment is equipped with a magnetic coil, which is magnetized to attract the bearing end face by magnetic force, but it is unable to attract and fix the non-magnetic ring for processing, thus reducing the processing accuracy of the non-magnetic ring. Utility Model Content

[0004] In order to improve the problem of machining accuracy of non-magnetic rings, the present application provides a clamping tool for machining non-magnetic bearings.

[0005] The present application provides a clamping tool for processing non-magnetic bearings, which adopts the following technical solution:

[0006] A clamping tool for processing non-magnetic bearings includes a magnetic seat, the bottom of which can be magnetically adsorbed and fixed on a magnetic coil, the magnetic seat has a positioning cavity for the non-magnetic ring to be embedded, and the inner wall of the positioning cavity can abut the outer periphery of the non-magnetic ring to form a limit.

[0007] By adopting the above technical scheme, when the non-magnetic ferrule needs to be processed, the bottom of the magnetic seat is first fixed on the magnetic coil by magnetic adsorption to achieve fixation of the magnetic seat on the processing equipment, and then the non-magnetic ferrule is embedded in the positioning cavity. The circumferential outer wall of the non-magnetic ferrule abuts against the inner wall of the positioning cavity to form a limit, thereby achieving the limit of the non-magnetic ferrule, making it difficult for the non-magnetic ferrule to shift during processing, thereby improving the processing accuracy of the non-magnetic ferrule.

[0008] Optionally, the magnetic seat includes a magnetic outer cone sleeve and an inner cone sleeve, the end face of the magnetic outer cone sleeve can be magnetically adsorbed and fixed on the magnetic coil, the positioning cavity is located on the inner cone sleeve, the magnetic outer cone sleeve has a limiting cavity for the inner cone sleeve to be embedded, and the inner wall of the limiting cavity can abut the outer periphery of the inner cone sleeve to form a limit.

[0009] By adopting the above technical scheme, the inner tapered sleeve is embedded in the limiting cavity, the inner wall of the limiting cavity abuts against the outer periphery of the inner tapered sleeve to form a limit, the non-magnetic ring is embedded in the positioning cavity, the inner wall of the positioning cavity abuts against the outer periphery of the non-magnetic ring to form a limit, and the end face of the magnetic outer tapered sleeve is magnetically adsorbed and fixed on the magnetic coil. When the inner wall of the positioning cavity is worn and needs to be replaced, only the inner tapered sleeve needs to be replaced, and there is no need to replace the entire magnetic seat, thereby reducing the waste of materials and thus reducing the cost of using clamping tooling for processing non-magnetic bearings.

[0010] Optionally, the magnetic seat also includes a locking nut, the inner ring of the locking nut is provided with an internal thread, the outer circumference of the inner tapered sleeve is provided with an external thread meshing with the internal thread, the inner tapered sleeve is provided with a plurality of deformation grooves spaced circumferentially, the deformation grooves penetrate the outer wall of the inner tapered sleeve in the depth direction and are connected to the positioning cavity, when the locking nut thread is tightened and fixed on the outer circumference of the inner tapered sleeve, the inner wall of the positioning cavity is driven to deform toward the non-magnetic ring and press against the outer circumference of the non-magnetic ring to form a limit.

[0011] By adopting the above technical scheme, when the workpiece is embedded in the positioning cavity, the inner circle thread of the locking nut is tightened and fixed on the outer periphery of the inner tapered sleeve to form a fixation, and the inner circle of the locking nut squeezes the outer periphery of the inner tapered sleeve, driving the inner wall of the positioning cavity to deform in the direction close to the non-magnetic ring and press against the outer periphery of the non-magnetic ring to form a limit, and the deformation groove is connected to the positioning cavity, and the deformation groove provides a deformation space for the positioning cavity, so that the inner tapered sleeve is not easily deformed and broken under pressure, thereby extending the service life of the inner tapered sleeve.

[0012] Optionally, a deformation gap is formed on the inner wall of the deformation groove away from the internal thread, and the deformation gap is connected to the positioning cavity.

[0013] By adopting the above technical solution, the deformation gap is located at the inner wall of the deformation groove away from the internal thread, so that when the inner circle thread of the locking nut is tightened and fixed to the outer periphery of the inner tapered sleeve, the deformation space is further increased for the compressive deformation of the inner wall of the positioning cavity, the elasticity of the inner tapered sleeve is improved, thereby extending the service life of the inner tapered sleeve.

[0014] Optionally, a guide cone surface 1 is provided on the outer periphery of the inner tapered sleeve, and the inclined distance from the guide cone surface 1 to the axis of the inner tapered sleeve decreases as the distance to the locking nut decreases; a guide cone surface 2 is provided on the inner wall of the limiting cavity, and the inclined distance from the guide cone surface 2 to the axis of the magnetic outer tapered sleeve decreases as the distance to the locking nut decreases; when the inner ring thread of the locking nut is tightened and fixed on the outer periphery of the inner tapered sleeve, the guide cone surface 2 abuts against the guide cone surface 1 and guides the inner tapered sleeve to slide on the inner wall of the limiting cavity, thereby driving the inner wall of the positioning cavity to deform toward the direction close to the non-magnetic ring.

[0015] By adopting the above technical scheme, the non-magnetic ring is embedded in the positioning cavity, and the circumferential outer wall of the non-magnetic ring abuts against the inner wall of the positioning cavity to form a limit, and at the same time, the guide cone surface one abuts against the guide cone surface two, and the inner thread of the locking nut is tightened and fixed on the outer circumferential surface of the inner tapered sleeve. The inner ring of the locking nut squeezes the guide cone surface one, and the guide cone surface two abuts against the guide cone surface one and guides the inner tapered sleeve along the guide cone surface two to approach the locking nut, driving the inner wall of the positioning cavity to deform in the direction close to the non-magnetic ring, and the inner wall of the positioning cavity abuts against the outer circumference of the non-magnetic ring to form a limit, so that the non-magnetic ring is not easy to deviate in the positioning cavity, thereby improving the processing accuracy of the non-magnetic ring.

[0016] Optionally, the cone surface roundness requirements of the guide cone surface 1 and the guide cone surface 2 are both less than or equal to 1.

[0017] By adopting the above technical solution, the cone roundness requirements of guide cone surface one and guide cone surface two are both less than or equal to 1, so that guide cone surface one and guide cone surface two can be completely abutted and matched, and guide cone surface two is evenly stressed on guide cone surface one, thereby improving the stability of the uniform stress deformation of the inner wall of the positioning cavity.

[0018] Optionally, a plurality of bayonet holes are provided at intervals on the outer circumference of the locking nut, and the bayonet holes are used for the clamp to be embedded and clamped.

[0019] By adopting the above technical solution, when the inner ring of the locking nut is arranged on the outer periphery of the inner tapered sleeve, the clamp is embedded in the bayonet and clamped to fix the clamp on the locking nut. The clamp drives the locking nut to rotate, and the locking nut is not easy to slip when rotating, thereby improving the stability of tightening the locking nut and the inner tapered sleeve thread.

[0020] Optionally, the positioning cavity includes positioning segment one and positioning segment two, and a step surface is formed at the connection between the positioning segment one and the positioning segment two. When the non-magnetic ring is embedded in the positioning segment one, the step surface can abut the end face of the non-magnetic ring to form a limit.

[0021] By adopting the above technical solution, when the non-magnetic ring is embedded in the positioning section one, the end face of the non-magnetic ring abuts the step surface to form a limit, so that the non-magnetic ring is not easy to shift in the positioning section one, thereby ensuring the stability of the processing of the non-magnetic ring and improving the processing accuracy of the non-magnetic ring.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The setting of the magnetic seat can realize the fixation of the magnetic seat on the processing equipment, so that the non-magnetic ferrule is not easy to deviate during processing, thereby improving the processing accuracy of the non-magnetic ferrule;

[0024] 2. The setting of the magnetic outer tapered sleeve and the inner tapered sleeve eliminates the need to replace the entire magnetic seat, reducing material waste and thus reducing the cost of clamping tooling for machining non-magnetic bearings;

[0025] 3. The setting of the locking nut and the deformation groove provide deformation space for the positioning cavity, so that the inner cone sleeve is not easily deformed and broken under pressure, thereby extending the service life of the inner cone sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

The aperture of the positioning section 111 is smaller than the aperture of the positioning section 2 112. A step surface 113 is formed at the connection between the positioning section 111 and the positioning section 2 112. The step surface 113 can abut the bottom of the non-magnetic ring 2 to form a limit, so that the non-magnetic ring 2 is not easy to deviate in the positioning section 111, thereby improving the limit stability of the non-magnetic ring 2 in the positioning section 111.
